Kaf

Kaf released BLUE SIGNAL as Azur Lane's 9th anniversary song on September 7, 2026. She is also confirmed for NIGHT HIKE 2026 at Makuhari Messe on October 31 and November 1.

Synthesized from 5 Yomimono stories · updated Sep 11

Kaf's recent work runs through collaborations and festival bookings. On September 7, 2026, she released BLUE SIGNAL as the 9th anniversary song for Azur Lane, with writing and composition by Kanata Okajima and Shuya Masayoshi. The song was announced at her 5th ONE-MAN LIVE and the AZUR LANE SPECIAL MUSIC LIVE, both held the same day.

That followed a promotional video for the game meat restaurant Kome to Circus, posted September 1. Kaf eats sea turtle soup and meat she was not told about, calling them 'unconfirmed tastes.' KAMITSUBAKI STUDIO producer PIEDPIPER appears with her. The collaboration came from Kaf's earlier visits to the restaurant and the staff's history as her fans.

Her festival schedule includes NIGHT HIKE 2026, announced in a second wave of performers on July 24. Ten acts joined, among them Kizuna AI, Shinichi Osawa, and the Utsu-P meet siinamota tribute project with Sou on guest vocals. With the first wave, 47 acts are confirmed for October 31 and November 1 at Makuhari Messe International Exhibition Halls 9 and 11. Sana Natori and KMNZ were announced earlier.

Two other stories in the cluster concern Ekimae no Kafka, a command-input adventure game by Neji. Games, and Bungo Stray Dogs Wan! 2, whose ending theme Kensho Ono performs. Kaf is not connected to either.
